Embodiment Construction
[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0023] In order to clearly understand the solution of the present invention, the virtual network and its dhcp service in the network attack and defense platform are firstly introduced. A virtual network is a network composed of one or more virtual machines, on which online game questions are deployed, and different game questions are deployed in different virtual networks. Each virtual network in the network attack and defense platform will be is...

The invention discloses a network attack and defense platform port mapping method and system, and belongs to the technical field of networks. The method comprises the following steps: creating a namespace of dhcp service on a control node, and connecting the namespace and a virtual network bridge through a virtual network card pair of linux; configuring an ip for the virtual network card in the namespace and taking the ip as a gateway ip of the virtual network; and when newly establishing port mapping, combining soat and nc tools, using nc to connect to a certain port of a specified virtual machine in a namespace, and using soat to connect a port distributed on a control node and nc in the namespace, wherein after the port mapping is established, players can access the game questions in different virtual networks by accessing the control node ip and different ports. According to the method, the virtual machine network and the physical cluster network are connected, so that the port of the virtual machine in the game environment can be exposed, the purpose of port mapping is achieved, and the method has the advantages of being easy to manage and high in flexibility.
Description
technical field [0001] The invention relates to a port mapping method and system of a network attack and defense platform, belonging to the field of network technology. Background technique [0002] The network attack and defense platform provides a highly simulated information security attack and defense combat drill environment through virtualized scenarios, which can meet the needs of customers in various industries for information security confrontation drills and competitions. When using the offensive and defensive platform to hold a game, for the online environment, different players will have different game environment. When there are many players, each game environment is configured with an IP, which will occupy too many public network IPs and increase The cost of the game. The available solution is that different test environments share a public network ip, and the test questions are exposed through different ports of the public network ip, so that everyone can acc...
